Should I change stem length for lift service runs?

I'm hitting up a nearby resort for some lift service runs in a couple weeks and am contemplating changing out my front stem to a shorter one I have. Currently riding a Yeti ASR7 (which has a 67deg head angle with 160mm fork) with a 90mm stem and I have a 50mm stem I'm thinking of putting on. I just don't have any riding time on the 50. Will I be changing the handling too much and jeopardizing me crashing more?

I've only done lift service once before at a different resort and on a completely different bike. (Yeti 575, all air suspension, as opposed to my new ASR 7, all coil)

It could throw the handling off ...making it more "twitchy" if using the same bars.
Should think about getting wider bars also to offset the quicker steering.
I'm not sure why the went to shorter stems in the first place...for more strength?
If you are not going to big you might try it as is..but take the shorter stem also.

Throw it on for a driveway test ride or throw it in your bag for a test ride out on the trail. Only takes a couple minutes to change the stem, throw it on at the top of a decent somewhere in your local trail system and see how it feels.

Don't you hate it when a sentence doesn't end the way you think it octopus?

As it ends up, I did have 685mm bars (MonkeyLite Carbon XC). They're 3 years old and have seen a few hits, so I rationalized buying new. Easton Havoc Carbon 740mm. I can always cut them down if I decide to later. Gonna try to get a couple local rides in on trails I ride frequently for an accurate comparison. Thanks for the help.

Yeah that's about as low as it goes, it's a long post. Wasn't a problem with RockShox Reverb, but it took a dump on me for the second time and is off for warranty. Might have to cut down the seat post...
